After the release the of Xperia XZ2 in the Mobile World Congress held at Barcelona, Spain between 26 Feb 2018 - 1 Mar 2018, the Japanese technology company Sony has unveiled its next "Xperia XZ2 Premium" as an up-gradation. It's the direct successor of the Xperia XZ Premium that was known for its 4K display.

The Sony Xperia ZX2 Premium: lots of pixels, miles of bezel. The company has brought forward a dual-camera to its 5.8-inch flagship and we will be looking at extensive details on what could be the best-selling point of the entire smartphone.

Now, let's talk about the biggest upgrade in the XZ2 Premium; its camera. The "vanilla" Xperia XZ2 and Xperia XZ2 Compact are scheduled to officially launch in the USA on May 6, so we'd imagine buyers pining for the version with a 4K screen will have to wait at least until then. However, the feature would be absent at launch, and only be included during the third-quarter update.

For video capture, the ISO sensitivity level can go up to 12800 and for still-image shooting, you can go up to an impressive 51200.

Despite its hefty price tag, it looks like the XZ2 Premium will stand out with its improved specs, enhanced camera, and 4K HDRdisplay at a time when the lines between phones are becoming increasingly blurry. It measures 158x80x11.9mm and weighs 236 grams.

The phone is powered by Octa-Core QualcommSnapdragon 845 with Adreno 630 GPU. On the storage front, the device offers 64GB of internal storage that is further expandable up to 400GB via a microSD card slot. The phone is also water resistant and supports wireless charging - in other words, it's very similar to the Xperia XZ2 aside from the features we've mentioned above. The physical scanner is located at the same place like other smartphones at the rear panel. The color sensor is 19MP while the monochrome sensor is 12MP. The Sony Xperia XZ2 Premium now has a 5.8 inch IPS LCD display with a 4K resolution.

On the front there is a 13-megapix camera with f / 2.0 aperture and 22mm wide angle lens. Just like the XZ2 Premium, the display supports HDR.

The smartphone will be available globally from Summer 2018 in Chrome Black and Chrome Silver colour options. What are your opinions on the design and the specs?

Pricing also hasn't been revealed but, assuming it ships to the U.S., we'd expect it to be a fair whack more expensive - think up to $1000 and at least $900, compared to the XZ2's $800 unlocked asking price in the States.
